本文对SKA（平方公里阵）抛物面天线的馈源喇叭进行了优化设计，提出了一种基于天线灵敏度的宽外展波纹喇叭的优化设计方法。研制了波纹喇叭样机，测试了其回波损耗和辐射方向图。实测结果与计算结果吻合较好，验证了分析和设计方法的正确性。
In this paper, the optimization of the feed horn for the SKA (Square Kilometre Array) dish is presented, and an optimization method based on the antenna sensitivity for wide-flared corrugated horn is proposed. A prototype of the corrugated horn is developed and the return loss and the radiation patterns are tested. The measured results show a good agreement with the calculated ones, which validates the analysis and design method.
